JERSEY v Application filed July 6, .1931;

This invention relates to machines for use is illustrated herein as embodied in a machine having a gage particularly adapted for use in attaching hank stifleners to boots and shoes. r. r s

In the manufacture of boots and shoes it is customary to attach shank stiffeners to the insoles of theboots and shoes prior to the laying of the outsoles by means of fastenings which passthrough the stiffeners and through theinsoles. Metallic shank stifl'eners are provided with apertures for the reception of the fastenings and when the fastenings are driven by theme of fastening inserting machines, it is important that the apertures in the shank pieces be accurately alined with'the fastening inserting means of the machines. When applying shank stiffeners of the type described and claimed in a copending application, Serial No. 530,914,filed April 17,1931, in the names of Leroy W. Rollins and Arthur S. Johnson, in which the sides of the fastening receiving apertures are formed ,to provide deflecting surfaces for the legs of the fastenings, it becomes increasingly important that the apertures be accurately alined with the fastening inserting means of the machine to insure that the legs of the fastenings will be properly deflected and be caused to curl without penetrating through to the other surface of the insole.

One object of this an improved device for positioninga memberhavi'n'g fastening receiving'apertures relatively to the'fastening inserting means 0 a machine whereby the fastening receiving apertures are accurately alined with the fas tening inserting means.

In accordancewith this object onefeature of this inventionresides in a fasteninginserting machine having fastening. inserting means, a member adapted to position a work piece longitudinally relatively to the" fastenand means constructed and arranged to position the work. piece transversely relatively to the fastening inserting means whereby fastening receiving aperturesin the work piece are brought into alinement with the fastening. inserting bracket adjacent to the invention is to provide 01 BEVERLY, MASSACHUSETTS, ASSIGNOR TO SHOE OF PATEBSON, NEW JERSEY, A CORPORATION OF NEW FASTENING INSERTING MACHINE Serial No. 548,736.

means. As herein illustrated, the means for positioning the work piece are mounted on a bracket secured to the throat piece of a fastening inserting machine, the free end of the bracket having adj ustably secured thereto a resilient spring-like member having an end portion extending at an angle to the main portion of the member for engaging the end of the stiffener to position the stiffener longitudinally, and secured to the throat piece are a pair of members which are adjustable toward and from each other to accommodate shank stilfeners of different widths, these members being adapted to position the shank stiffener transversely.

Other objects and features of the invention will appear from the following description and claims when considered in connection with the accompanying drawing, in which Fig. 1 is a perspective view-ofone emb0d-i ment of the invention; 7 V a Fig. 2 is a sectional view taken along the line II-II of Fig. 3; i :1

Fig. 3 is a longitudinal sectional view taken along the line III-+111 of Fig. 2; and

f complete description of theparts not fully described herein. The machine comprises a nozzle or throat piece 10 through which staples pass for insertion into the work, the staples being inserted'into the work by a driver 12 which is rcciprocated upwardly and downwardly in suitable guides in the mach ne frame. The throat piece 10 is formed in two parts 14 and 16 which are secured together by means of screws or studs 18.

The shank piece or stiffener 2O disclosed in the above-mentioned application is provided with fasteningreceiving apertures 22 having their walls formed to provide dee fleeting surfaces for the legs of a staple 24 so that when the staple is inserted through the apertures 22 by the driver 12 the legs of the staple are curled inwardly and clench beneath the bar ofthe staple in such a manner as most efiectively to resist displacement and thus securely to hold the .stiffener in place on an insole 26. As shown in Fig. 3, the apertures 22 may be spaced longitudinally of a narrow stiffener, or, as shown in Fig. 4, the apertures may be spaced transversely of a wide stiffener.

The gage for positioning the stiffener in proper position beneath the driver 12 with the fastening receiving apertures 22 in alinement with the driver bar 12 includes a bracket 28 which has an extension 30 at one end through which pass the screws 18. The bracket is rigidly held in place on the throat piece by means of nuts 32 which are threaded on the screws 18. The end 34 of the bracket is provided with a downwardly extending portion 36 provided with threaded holes which receive cap screws 38. An end gage 40 for the stiffener is provided with a slot 42 at one end through which the screws 38 pass adj ustably'to secure the end gage to the bracket 28. The end gage is formed of spring steel and, as shown in Fig. 3, is provided with an angular portion 43 against which the end of the stiffener 20 is placed. The angular portion 43 is normally located below the plane of the lower end of the throat piece 10 and is adapted to yield upwardly when the insole 26 is pressed thereag'ainst.

The end of the bracket adjacent to the throat piece 10 is provided with an enlarged portion 44 which is shaped at its lower surface to provide a guideway for a pair of lateral gages 46. These lateral gages are each providedat their upper ends with extensions 48 having oppositely threaded holes. An adjusting screw 50 havingoppositely threaded portions is passed through the oppositely threaded holes in the extensions 48 and rotation of the screw 50 will cause the gages 46 to be moved toward and from one another to accommodate shank stiifeners of different widths. The adjusting screw 50 has a reduced portion substantially centrally of its length into which fits a U-shaped retaining member 52 which prevents axial displacement of the screw relatively to the bracket 28. The retaining member is secured to the bracket 28 by means of a cap screw 54 which passes through an extension formed as a part of the retaining member 52.

The construction described above is adapted to be used in locating the fastening receiving apertures of av shank piece in alinement with the fastening inserting means of the machine when the apertures are spaced longitudinally of the stiffener. When using relatively wide shank stiffeners it is sometimes desirable to position the fastening res ceiving apertures transversely of the shank.

The construction shown in Fig. 4 is particularly adapted for use in alining transversely spaced apertures with respect to the fastening inserting means of the machine. The modification shown in Fig. 4 is substantially the same as that shown in Fig. 1 except that the bracket 28 is not provided with an extension 30 for securing the bracket to the throat piece 10. The enlarged end portion 44 of the bracket is provided with holes through which the screws 18 pass and the nuts 32 secure the brackets in place'on the throat piece 10. The bracket 28 shown in Fig. 4 is secured inposition at right angles to the position shown in Fig. 1 and when a shank stiffener having transversely spaced apertures is being used the end and lateral gages 40 and 46 will properly position the apertures with respect .to the fastening inserting means.

While the parts of the device have been described in detail, it may be well to summarize briefly the operation of the device. The operator places a shank stiffener in proper position on an insole and, while holding the shank stiffener in position, places one end of the shank stiffener against the downturned portion 43 of the gage 40 in a plane below the working position, thus positioning the shank piece longitudinally with respect to the driver 12. Then the work, due to the resiliency of the member 40, is directed between the side or lateral gages 46 which have been adjusted to the proper width. These engage the sides of the stiffener and locate it transversely. When the shank stiffener has been positioned, the operator treadles the machine, causing the driver bar to move downwardly and insert a staple through the stiffener. The legs of the staple engage and are deflected by the walls of the apertures and are clenched beneath the stiffener. The shank stiffener and insole may then be turned end for end and another staple may be inserted in apertures in the other end of the stiffener.
